yeah, swapping isn't an issue.. but just doing research i will need new axles also.. the pre-64 open diff and suregrips used different lengths... also need to get some different 10" backing plates for my drums.. so staying with awesome 2.89 gears for now :) I think the future will be 3.55s
I think that's what's in my 8.25 but open diff. Want to find a sure-grip for it. Probably depends on tire size a bit but is 3.55 street or strip, wonder how it will be with 340 and 904 trans
